At Abel Tasman National Park you can book a fun kayaking trip & then drive along the west coast. Don't forget to visit Punakaiki near Paparoa National Park for even more amazing views.
Thrill seekers can book a glacier heli-hike to explore on Franz Josef Glacier & Fox Glacier. It's the best glacier experience in New Zealand! Then try an evening soak in Glacier Hot Pools.
Head to Queenstown via Wanaka for the views. In Queenstown, you can book a fun jet boat tour on the river or try bungee jumping! Then head toTe-Anau and the beautiful Milford Sound.
Once you get to Milford Sound, you'll cruise for a couple of hours on the famous fjord spotting wildlife like seals and dolphins amongst towering cliffs and soaring waterfalls.
Head to Lake Pukaki where you can see this glacially-fed milk-blue lake with fantastic views of Aoraki/Mount Cook behind it. My favorite nearby hike was the Hooker Valley Track.
Central Otago and Aoraki
Lake Tekapo during lupin season is magical and definitely worth a visit on your way to Christchurch. Once there, you can walk the city looking at local street art and stroll the Botanic Gardens before heading home.
More Things To Do
If you have time, I recommend going to The Coromandel Peninsula to explore the Hot Water Beach and the famous Cathedral Cove or the Bay of Islands.
